Sharing a Google calendar
I am trying to share a google calendar with a group of work colleagues without luck.
I have google apps for ed setup.
In the calendar under my user name I have created a new calendar called shared calendar.
In contacts I have created a group of users called sharedusers
in calendar settings under 'Share with specific people' I have entered my group using firstname.lastname@example.org
but in a colleagues calendar my shared calendar does not show. If I go to the 'other calendars' section (still logged in as my colleague) and type in my username (I am the one that created the shared calendar) it says that I do not have access to this calendar.
What am I missing.
